The strong consensus is that there is no canvas yet available you should be comfortable not coating for pigment inks. Solvent or latex inks may be a different story - I haven't looked at those much.
Many satin or gloss canvases claim you can get by without coating. One of the manufacturers made the claim, and many of the others' marketing departments decided to make the same claim.
You can find countless threads here of printers complaining about losing so many canvases that were uncoated, and the manufacturers shrugging their shoulders when it happens.
That being said, if you're printing it, carefully stretching it, and putting it straight on a wall... You may get away with it. Sometimes.
If you're shipping it, exhibiting it, etc, there's no point to even try.
